DWPI: Latest Manual Code Revision goes live

09. January 2015
The Derwent World Patents Index® (DWPISM) manual coding system annual revision for 2015 is now complete and is being used by the editorial teams to code records appearing in the database from DWPI Update 201501 onward. The editorial team consistently applies DWPI manual codes to new inventions across all 50 authorities covered in the database. Since the coding highlights the novel technical aspects of the invention as well as the application(s), it is extremely useful to improve the precision and recall of searches and the subsequent analysis of result sets.

As with previous revisions, the coding has been updated to:

  • Reflect changes in technology
  • Take into account suggestions for improvements
  • Enhance code descriptions and scope notes to improve the consistency of code application by the editorial teams and understanding of what each code covers.
  • 2,040 changes have been made to DWPI codes, including 1,956 new codes, as well as the updating of existing Titles, Scope notes and/or Search terms.

Major updates include:

  • 1,916 new codes have been introduced in the P & Q class coding hierarchy expansion
  • Several new sub codes for U14-H01E (Thin film transparent conductive layers) were included in the update following customer suggestions and discussions
  • Codes for CRISPR technology have also been included

The Coding Manuals and reference guides on the Thomson Reuters website
have all been updated to include the changes. These resources are available at: ip-science.thomsonreuters.com/mcl/
